The disclosure herein generally relates to a case for a tablet shaped device, a method for removing a stylus therefrom, and a method for making a case for a tablet shaped device.

BACKGROUND

Cases for tablet shaped devices, examples of which include the APPLE IPAD, SAMSUNG GALAXY TAB, smartphones like the APPLE IPHONE, and some personal digital assistants, are commercially available. Some electronic tablet shaped devices have a touch screen and come with a stylus for drawing or writing on the touchscreen.

The commercially available cases for tablet shaped devices may not meet some of the needs of consumers, and may be more difficult and/or costly to manufacture than is desirable.

SUMMARY

Disclosed herein is a case for a tablet shaped device. The case comprises a body comprising a face having a tablet shaped device receiving area. The case comprises a stylus holder at a margin of the face for holding a stylus for the tablet shaped device. The stylus holder defines an elongate cavity for receiving the stylus. The stylus holder comprises at least one obstructing element arranged to obstruct removal of the stylus from the elongate cavity when so received.

In an embodiment, the stylus holder may be configured such that the stylus is below the face when so held. This may protect the stylus, which may be delicate and expensive.

In an embodiment, the at least one obstructing element is attached to an elongate cavity wall. The elongate cavity wall may be outwardly bendable and resilient. The at least one obstructing element attached to the cavity wall may be outwardly movable for removal of the stylus from the elongate cavity.

In an embodiment, a discontinuity in the elongate cavity wall provides finger access to the stylus when so received.

In an embodiment, the elongate cavity wall is integral to the body.

In an embodiment, the at least one obstructing element protrudes into the elongate cavity.

In an embodiment, wherein the at least one obstructing element comprises at least one rib. The at least one rib may be longitudinally orientated with respect to the elongate cavity.

An embodiment comprises another at least one obstructing element. The at least one obstructing element and the other at least one obstructing element may be distributed between opposite sides of the elongate cavity.

In an embodiment, the face is a rectangular face. The margin may be adjacent an edge of the rectangular face. The edge may be longer than another edge of the rectangular face.

Disclosed herein is a method for removing a stylus for a tablet shaped device from a case for the tablet shaped device. The method comprises moving the stylus towards an opening of an elongate cavity in which the stylus is received with a finger at a discontinuity in an elongate cavity wall having attached thereto an obstructing element arranged to obstruct removal of the stylus from the elongate cavity. The stylus so moved engages an obstructing element arranged to obstruct removal of the stylus from the elongate cavity when so received and outwardly move the obstructing element for removal of the stylus.

In an embodiment, the elongate cavity wall outwardly bends when the obstructing element is outwardly moved and subsequently springs back when the stylus is removed from the tablet shaped device.

In an embodiment, a plurality of legs are located at another face of the body. The body may warp or distort during or subsequent to manufacture. The plurality of legs may provide stability when the warped body is placed on a flat surface. The legs may significantly relax manufacturing tolerances—for example the flatness of the rear—which may assist in the control of manufacturing costs.

In the context of the present application, the term stylus encompasses a hand-held tool used by a user to interact with a touch sensitive area (for example a touch sensitive screen) of the tablet shaped device. An example of a stylus may, but not necessarily, comprise an elongated shaft having opposite ends and a touch sensitive area interaction point at at least one of the opposite ends. The point may be rounded. A stylus may be active, passive, or haptic, for example.

DESCRIPTION OF EMBODIMENTS

The FIGS. 1-8 show various views of a case for a tablet shaped device in the form of a case for an electronic tablet shaped device, the case being generally indicated by the numeral 10. The case 10 comprises a body 12 comprising a face 14 having a tablet shaped device receiving area 18. The case 10 comprises a stylus holder 20 at a margin 22 of the face 14 for holding a stylus (e.g. Apple Pencil) for the tablet shaped device. The stylus holder 20 defines an elongate cavity 24 in the form of a groove for receiving the stylus. The stylus holder 20 comprises at least one obstructing element 26 arranged to obstruct removal of the stylus from the elongate cavity 24 when so received.

The stylus holder 20 is configured such that the stylus is below the face when so held. The depth of the bottom 27 of the elongate cavity is, in this but not all embodiments, at least (and may be greater than) a transverse dimension of the stylus or another stylus usable on a tablet shaped device receivable by the case for a tablet shaped device 10.

The at least one obstructing element 26 is attached to an elongate cavity wall 28 in the form of an outer edge cavity wall. The elongate cavity wall 28 can be outwardly bent and is resilient.

The elongate wall may be bent in a direction orthogonal to a normal to the face 14. Alternatively or additionally, the obstructing element may be resilient. The at least one obstructing element 26 attached to the cavity wall 28 is outwardly movable, when the cavity wall 28 bends outwardly, for removal of the stylus from the elongate cavity 24. A discontinuity 30 in the elongate cavity wall 28 provides finger access to the stylus when so received. The discontinuity may cut into the bottom wall 27 of the elongate cavity 24. The discontinuity is intermediate opposite edges of the case 10, in this embodiment located at the centre of the margin 22.

In this but not all embodiments, the elongate cavity wall 28 is integral to the body 12. The at least one obstructing element 26 protrudes into the elongate cavity 24, however it may alternatively be above the elongate cavity 24.

The at least one obstructing element 26 comprises at least one rib 26, however the at least one obstructing element may take the form of a bump, bulge or generally any suitable form. The at least one rib 26 is longitudinally orientated with respect to the elongate cavity 24, however it may not be in an alternative embodiment. In this but not necessarily all embodiments, the rib 26 is located at an edge of the elongate cavity to form a lip. The at least one obstructing element 26 and another at least one obstructing element 34 are distributed between opposite sides 36,38 of the elongate cavity 24.

The face 14 is a rectangular face 14, notwithstanding rounded corners. The margin 22 is adjacent an edge 40 of the rectangular face 14 that is longer than another edge 42 of the rectangular face 14.

An embodiment of a method for removing the stylus for the tablet shaped device from a case 10 for the tablet shaped device will now be described. The stylus is moved towards an opening 44 of the elongate cavity 24 in which the stylus is received with a finger at the discontinuity 30 in the elongate cavity wall 28 having attached thereto an obstructing element 26 arranged to obstruct removal of the stylus from the elongate cavity 24. The stylus so moved engages the obstructing element 26 arranged to obstruct removal of the stylus from the elongate cavity 24 when so received and outwardly move the obstructing element 26 for removal of the stylus.

The elongate cavity wall 28 outwardly bends when the obstructing element 26 is outwardly moved and subsequently springs back when the stylus is removed from the tablet shaped device.

In this but not necessarily all embodiment, the body has a perimeter wall 46 and a rear wall 48 that protect the tablet shaped device when so received by the tablet shaped device receiving area 18. The perimeter wall 46 and the rear wall 48 have a plurality of optional ports 50 for cable or other access to the tablet shaped device when received.

The perimeter wall 46 has a resilient lip 53 located at a distal end thereof. The perimeter wall 46 and the tablet shaped device receiving area 18 define a cavity in which the tablet shaped device is held by the resilient lip 53. The opening of the cavity is constricted by the resilient lip 53. The tablet shaped device may be inserted into the cavity by squeezing it through the opening defined by the resilient lip 53. The resilient lip 53 deforms to accommodate the passage of the tablet shaped device, and recoils back into shape subsequent to passage of the tablet shaped device. In another embodiment the tablet shaped device may be held to the tablet shaped device receiving area 18 by at least one elastic strap or generally by any suitable fastener.

The tablet shaped device receiving area 18 has an optional inner lining in the form of a inner felt lining. The inner lining provides a relatively soft surface to reduce scratching of the tablet shaped device. Other embodiments may not have an inner lining or may have another suitable lining material.

The rear of the body 12 has another face 54 that has a plurality of legs 52 projecting therefrom. The legs 52 provide stability when the case 10 is resting on a flat surface with the legs 52 on the flat surface. The surface may be, for example, a bench top table top, or any other suitable surface at which a user may place the case and use the tablet shaped device held therein.

The case 10 may be made using generally any suitable method. An embodiment of making a case for a tablet shaped device has the step of forming a body comprising at least a first material. The step of forming the body may comprise forming the body by an injection moulding process.

At least one polymer—for example a polyurethane, polycarbonate or generally any suitable polymer—may be injected into a mould configured for production of the body. The illustrated embodiment has a body formed by injection moulding. The body has a polycarbonate exterior and a polyurethane interior. The polyurethane is relatively soft for receiving the tablet shaped device. The relatively resilient polyurethane facilitates insertion and removal of the device and providing a degree of shock resistance against knocks and falls. The polycarbonate exterior forms a hard protective shell.

FIGS. 9 and 10 show rear and front perspective views of another embodiment of a case for a tablet computer 100 that has a flap 102. The case 100 is generally identical to the case 10 of FIGS. 1-8 unless otherwise described or illustrated. The flap 102 comprising a distal portion 104 in the form of a wing that is magnetically attracted to the body 106, and configurable between a first configuration in which the flap covers the tablet shaped device receiving area and the distal portion 104 is wrapped around an edge 108 of the body 106 and contacts the back face such that the flap is secured by the magnetic attraction of the distal portion 108 to the body 106, and a second configuration in which the flap 102 is folded to form a stand secured by the magnetic attraction of the distal portion 104 to the body.

When the flap 102 is in the first configuration, it protects a front of the tablet shaped device when received by the receiving area. The case 100, when the flap 102 is in the second configuration, supports the tablet shaped device when received at an elevated angle with respect to a case supporting surface.

Securement of the flap 102 by the magnetic attraction may facilitate relatively easy and rapid reconfiguration between the first configuration and the second configuration.

The distal portion 104 comprises a distal portion magnet having a magnetic orientation in the first configuration that is reversed in the second configuration. The distal portion magnet may be attracted to a first body magnet in the first configuration and, in the second configuration, to a second body magnet having a magnetic orientation that is reversed with respect to the first body magnet.

In the second configuration the flap is folded and located at the first face. The flap comprises a first rigid sheet that in the second configuration is a base of the stand. The flap may comprise a second rigid sheet that in the second configuration is a brace of the stand.
